In Canada June 6, 1946 "Introduction The invention relates to atomizers,and more particularly to a portable atomizer for dispensing perfume. A

The invention comprises an atomizing nozzle which is simple tomanufacture and assemble as well as easy to maintain. The. majority ofpocket atomizers, which are adaptable for dispensing perfume, comprise,along with the fluid reservoir and pump, a. tube .connected with thefluid reservoir and another tube. through which air is, pumped. As theproper atomizer function depends upon the relative position of the ends'of these tubes,.proper adjustment is difficult to maintain, and as thetube connected with the fluid reservoir would permit free leakage of thefluid, it has been necessary to cover the end of this tube for atomizerswhich were to be, carried in the pocket or purse.

As will be understoodthe adding of movable 7 parts likely to becomedeformed, makes continual maintenance necessary.

Objects An object of this invention is the provision of an atomizingnozzle which is contained within the body of the-atomizer, and whicheliminates the use of any moving parts suchas a cover.

A further object of this invention is the provision of a perfumeatomizer which is simple in construction and. simple in operation.

Another object of thisinvention is the construction of an atomizer bodyfrom a single billet of alloy material, impervious to perfume, whichprovides for cheaper manufacture.

Preferred structure A preferred structure fulfilling the'objects of thisinvention comprises a thin substantially rectangular casing, made from asolid billet of material, in which borings constitute a fluid chamber, apump cylinder, and a recess which holds the atomizing nozzle incommunication with fluid chamber and the pump cylinder. The atomizingnozzle, which will be more fully explained later, comprises two parts,namely a primary body member and a secondary insert. Borings andclearances withinand between the primary and secondary members providean air passage and a fluid passage, which in conjunction with a pistonworkable in the pump cylinder, dispenses perfume in atomized or sprayform.

Detailed description Still other features will be apparent in the courseof the following detailed description in which reference is made to theaccompanying drawings, wherein:

Figure 7 is an end view of the secondary insert member showing the flatson the bevel face of this member.

Referring to Figure 1 of the drawing, the,cas-

ing I0 is a solid billet of material in which the vertical boring l2forms a fluid chamber and the V verticalboring [4 forms a pump cylinderwhich are connected to a horizontal, transverse boring IBby the passages18 and 20. The transverse boring I6 is closedat its rear end by a plug Il and. opens at its opposite, forward end through an oblique edgesurface l9 defining a relieved cornerportion ofthe generally rectangularbillet or casing I0. Forced, to a dry fit, into the opening of thechamber I 2, is a collar 22. A boring in. this collar is threadedtoreceivea closure 24, which is suitably sealed against leakage of fluidby a washer 26. A minute boring 28 in the collar 22 provides for theegress of air, from the fluid chamber I2, which is displaced as theclosure 24 is being screwed up to a point of ultimately sealing thechamber. Air may escape through the boring 28, up to the time of beingsealed by the washer 26. A lateralgroove 30 in the outside face of theclosure 24- is provided so that the closure may be tightened orunscrewed by the use of an ordinarycoin, I I

The piston which forms a movable part of the pumping mechanism comprisesa solid stem 32 which is threaded at one end to receive a washer 34.This washer 34 forms a base for a leather sealing ring 36 which has anupwardly extending 'collar, which is forced outwardly by a metalengaging head, consisting of a fluted wheel member 48 is retained on thelower end of the stem 32 by a snap ring 50 which is engaged in thedetents 52 on the wheel and 54 on the stem 32. Protruding wing members56which are formed on alternate quarters of the circumference of thewheel member 48, are caughtunder the flange head of a retaining screw.58 which is screwed into the body l0. As will be understood, a quarterturn of the head}!!! will release the wings .56 from'c'ontact with theretainer screw 58,'there'- *th'e'boring 72 in a dry fit sealing same.

3 by allowing the plunger to extend to an.

open positionby force of the spring 44.

Atomieer nozzle assembly is a reamed out beveled face joining theoutside 7 circumferences of the two bores as shown at 16.

Through the casing to the boring 12 'is a port 18 15 adapted tocommunicate with the boring iii in the body member 10, when the casing"ii! is forced into the open, enlarged end of the transverse passage [6.The-portion of this port 18 which communicates. with the fluidchar'nberv i2 is 20 countersunk at 80 to provide a globular formation tothe fluid as it enters the boring l2."

The secondary insert consists ofa'cylindrical member, of hollow plug, 82having a step-down*"- diameter, that isthe portion 84 is-ofa'circumference adapted to fit into the circumference of The diameter ofthe portion 86' is slightly smaller than the diameter of i2 or 84 sothat when the hollow plug 82 is inserted into the boring T2 thedifference in' circumferences form a 'chambe'rtii which is incommunication in the fluid chamber I2 by the boring i8 and the port 18which co "incide. The end of the insert 82 adjoining the circumference'86 is machined .down to'form a be'vel face fifi matching and fittingthebevel face Hi-in the primary member. A central boring 92 through thesecondary insert is connected with a smaller boring 94 completi t 1 'theinsertw-A' tube 96 having a minute central 40 orifice-is inserted in thesmall boring 94. This tube96 may beeliminated if the manufacturer findsthat-a boring ofsmall enough circumference L may be achievedany otherway. Flats 98 are .machined on the beveled surface 90, forming acommunication from the chamber 88 to the clearance between the outsidecircumference of tube ,96 and the boring 14. Withthe atomizer. nozzle,consisting of outer casing 10 and the innercylindrical.member-82 inassembled relation and disposedwithin the enlarged forwardend of thetransverse passage IS, the forward end of the nozzle projects throughtheoblique. surface I 9 of the block and lies With- .in-the. relievedcorner or, in other Words within 5 the. space defined by projections ofthe side and edgefaces of. the casing or billet l0.

Operation .The operation ofthis atomizer uses the same law which governsmost types of atomizers, namely that of a stream of. airpassing anorifice ,containing liquid and in so .doing drawing the liquid from itscontainer, the pressure of the air vapourizing the liquid as it is drawnout. As 55 will be noted, with reference to Figure 1, the air is forcedfrom the. pump cylinder through the borings 2D and I6. into the boring92 of the sec- 'ondary insert. and thence through the minute opening inthe tube 96.130 the atmosphere. .Perfume which has been allowed toenterthe chamber d8 of the nozzle, by shaking or normal. car.- rying of theatomizer-in a pocket or purse, is distributed around the circumference86. The passage of the air through the orifice in tube 9.6

, art.

llcauses the perfume to be drawn out past the j flats 98 and to mix withthe air in the opening 14 of the primary body member, the velocity ofthev pumped air causing the minute quantity of perfume to break up intoparticles and to emerge from the borings 14 with the air in an atomizedform.

Advantages As will be noted by the detailed description and theoperation of this atomizer, the only moving part for the operation ofthe atomizer is the piston of the pump. The tube 96 of the secondaryinsert of the nozzle is protected by the somewhat rounded :and bluntnose of the primary body member of the nozzle. Therefore, it will beseen that replacement or maintenance due to everyday use will be almosteliminated.

A further advantage of this type of atomizer is that the amount ofperfume which may be dispensed at any one time is limited to the amountof perfume which is held in the chamber 88 'in the nozzle assembly,therefore, there .is no chance of having the air stream draw a largequantity of perfume from the reservoir and deposit it more or less inits solid form.

In the preferred form tested, the clearance betweenthe circumference 86and E2 is approximately /1000 of an inch, therefore, limiting the amountof perfume contained within the chamber toa very minute quantity.

-A further advantage of this type. of atomizer is that with the use of asolid billet'forming the body, the collars 22 and 38 are driven tightlyinto the borings and the nozzle assembly is also assembled and fittedinto the body by a dry fit, thus eliminating all soldering and cuttingdown on the time and cost factor in manufacturing.

It will be understood that, without departing from the scope oftheclaims, various modifications may be made in the specific expedientsdescribed. .The latter are illustrative only, and not offered in arestrictive sense, it being desired that only such limitations shall beplaced thereon as may. be required. by the state of the prior Thesub-titles used throughout the specification are merely to simplifyreference thereto and should otherwise be disregarded.
